Excessive amount of higher alcohols in alcoholic beverages causes unwell and side-effect for consumers although adequate consumption offers joy and pleasure. Therefore, reducing higher alcohols in alcoholic beverages is necessary. We used nitrogen compensation to reduce higher alcohols with Chinese rice wine as an experimental model. Higher alcohols including isobutyl alcohols, isoamyl alcohols, and β-phenethyl alcohols were significantly decreased by 19.27, 23.03 and 19.43%, respectively, when 200 mg/L (NH4)2HPO4, 5% (w/v) yeast, and 11% wheat Koji were added to fermentation broth. Meanwhile, important quality parameters remained unchanged including free amino acids, organic acids, biogenic amines, and esters. The expression of glutamate dehydrogenase 1 gene (GDH1) and glutamine synthetase gene (GLN1) was significantly enhanced, 26.9- and 1.9-folds respectively. These results suggest that ammonium compensation could effectively decrease higher alcohols in Chinese rice wine by activating glutamate dehydrogenase (GDH) pathway in ammonium assimilation.The present study was conducted to investigate the ability of two probiotic strains, L. acidophilus PTCC 1643 and L. rhamnosus PTCC 1637, to bind aflatoxin B1 (AFB1, 20 ng/ml) in comparison with yogurt starter cultures, at equal bacterial count (~ 109 LogCFU/ml) during a 21-day storage period at 4 °C. All assessed treatments exhibited high percentages of AFB1-binding, ranged from 64.56 to 96.58%. However, the ability of probiotic bacteria was statistically higher than yogurt starter cultures. Aflatoxin binding ability of the selected lactic acid bacteria was dependent on both time and bacteria species. The highest and the lowest percentages of AFB1-removal was observed at 11th day of cold storage by L. rhamnosus (96.58 ± 3.97%) and at the first day of storage for yogurt starter cultures (64.56 ± 5.32%), respectively. The stability of bacterial cells-AFB1 complex was remarkable, since only 0.84-26.75% of bounded AFB1 was released from bacterial cells after 3 times washing during the storage period.Thyme oil in water nanomulsion was prepared under subcritical water conditions using water and saponin, as solvent and emulsifier, respectively. Gas chromatography revealed that there were 44 bioactive components in the extracted thyme essential oil which, thymol and carvacrol were two mains of them. Experiments were designed based on central composite design and effects of amounts of saponin and thyme essential oil were evaluated on particle size, polydispersity index (PDI) and zeta potential of the prepared nanoemulsions using response surface methodology. https://www.selleckchem.com/products/mek162.html Obtained results revealed that more desirable thyme oil nanoemulsions with minimum particle size (184.51 nm) and PDI (0.514), and maximum zeta potential (- 22.51 mV) were prepared using 0.94 g of saponin and 0.28 mL of thyme essential oil. Furthermore, results indicated that prepared nanoemulsion using obtained optimum production conditions had relatively high antioxidant activity (24%) and high antibacterial and antifungal activities against Staphylococcus aureus and Penicillium digitatum.This study investigated the effects of microbial transglutaminase (TG) and sodium alginate (AL) on the water-binding, textural and oil absorption properties of soy patties as a representative meat analog. The addition of TG increased all textural parameters and decreased the expressible moisture of the product. Alternately, AL showed the high water-binding properties of soy patties but caused a decrease in the textural parameters of the product. Both TG and AL were effective in reducing oil absorption during the frying of the product, particularly TG, which was more effective than AL. Therefore, the results indicated that TG and AL were involved in the quality modification of soy-based meat analogs, and palatable eating quality was obtained by combining optimal levels of the two binding agents.Squalene is a cancer chemo-preventive and skin protective agent with high commercial demand. Here, we report for the first time that the green tea (Camellia sinensis) leaves is a surprisingly rich plant-based source of squalene. Young and tender leaves and old and turf leaves were collected at four different collecting seasons (April-August). Lipophilic compounds in the leaves and commercial green teas were extracted with hexane. The squalene contents in the hexane extracts varied greatly with the types of the leaves and collecting seasons. The hexane extract of turf leaves contained significantly higher contents of squalene than the extract of tender leaves. The hexane extract of the turf leaves collected in August contained the highest content of squalene (29.2 g/kg extract). This represents the first report on the qualitative and quantitative information on squalene in green tea leaves.This study was carried out to investigate storage-associated changes in the fatty acid profile (with GC and 1H-NMR techniques) of oat-based gluten-free cookies prepared with different fats margarine (MAR), butter (BUT), lard (LAR), refined palm oil (RPO), refined palm oil with stearin (RPOS), and hydrogenated palm oil (HPO). GC analysis indicated that palmitic and stearic acid were the predominant saturated fatty acids (SFAs), regardless of the type of fat used. cis-Oleic acid represented the major monounsaturated fatty acid (MUFA), while cis-linoleic acid was the most abundant polyunsaturated fatty acid (PUFA). After 6 months of storage, a significant decreasing trend in SFA concentration was observed for LAR and RPOS cookies, while a decrease in MUFA concentration was observed only for HPO cookies. In fresh cookies and in cookies stored for 6 months, the contents of SFA, MUFA, and PUFA determined by GC were positively correlated with those determined by 1H-NMR (r &gt; 0.90).This study aimed to evaluate the influence of germination on the content of protein, lipids, fiber, ashes, tryptophan, vitamin C, total phenolic and total flavonoid compounds, as well as on the protein digestibility and antioxidant activity of chia seeds germinated for 1, 2, 3, and 4 days. The results showed that germination for 2 days augmented the protein content of chia seeds by 13% while fiber, tryptophan, total phenolic and flavonoid contents increased by 46%, 93%, 300%, and 197%, respectively, after 4 days of germination. Vitamin C was not detected in dry seeds but increased up to 2.33 mg/100 g at fourth day of germination. The antioxidant capacity increased approximately 100% but protein digestibility decreased by 14% at day 4 of germination. Germination can be a good method to increase the nutritional and nutraceutical potential of chia seed for its use in the design of functional foods.
